Okay so for those who's wondering if there's romance in here or not, watch the trailer in youtube. At 3:20 the subs said "a funny, romantic, and crazy investigation show". It might not end up with them getting married cause they both might not ready but we can defo see them getting comfortable first starting with ep 4 (yi eon getting mad when tae soo asked jo yi to kissed her). And in the preview of ep 5 tae soo said jo yi is yi eon's weakness.
I hope this makes sense, sorry my english isn't that good
